Interesting points. Few thoughts:
- Is a game plan that malleable that it can be switched/changed? For me, as a clubbie, if I play in the same spot, I play the way I play and I can't change it much.
- Change in technique works for me when I start working on it a season prior. Technique is muscle memory and building it takes time. But once, I have those reflexes trained, I can just go. So, it's slow and long to incorporate but easy to turn on/off during the game.
ok, well to focus on batting:
I would expect most successful club batsmen have different go-to shots against different types of bowlers. You might look to drive an offspinner but sweep a legspinner for example.
I would also expect a decent batsman to have the ability to change tactics on different pitches or in different situations - mostly this involves recognising that a particular shot is going to get you out and stopping playing it. If the ball is stopping in the pitch, put the drive away and just play with soft hands and drop for a single instead. If the ball is staying low from back of a length, put the pull shot away and play back with a vertical bat.
Most of the time the difference between a successful batsman and an unsuccessful batsman at club level isn't technique, its gameplan. I've seen guys with horrendous techniques score tons, simply because they had 2 shots and played them with absolute discipline. I've seen players with flawless textbook techniques get out cheaply week after week because they didn't have the knowledge to figure out what shots to put away on what type of pitch. They'd be bowled by every ball that kept low, and caught at cover driving anytime the ball stuck in the pitch. (I used to coach county juniors - most of them have this problem).
